The brackets or supports 9 and 10, which are mounted on the carriage at points below the rails, extend outward beyond the latter and receive the antifriction-wheels on their extended outer portions.

The reciprocating carriage is composed of a thin vertical body portion 12, a fixed horizontal top portion 13, and an adjustable extension or section .14, hinged at its inner end to the adjacent end of the top portion or plate 13 and adapted to be swung upward and downward for a purpose hereinafter ex plained. The thin vertical body portion of the carriage is provided with a vertical. groove or way preferably formed by vertical ribs 15, and receiving a projecting antifrictionroller 16, extending laterally from a sprocketchain 17, disposed longitudinally of the machine and adapted to carry the carriage backward and forward. The sprocket-chain 17 is arranged on a sprocket-wheel 18 and on a synocket-pinion 19, the sm'ocket-wheel being mounted on a longitudinal supporting-bar 21 and being located adjacent to the front of the machine or the end. adjacent to the glasstank, and the said sprocket 18 is of sufficient diameter to cause the carriage to remain at the front of the machine during the glassgatheringoperation a sufficient length of time to afford ample opportunity for such operation. The pinion 19 is rigid with and carried by a gear-wheel 20, suitably mounted on the simporting-bar 21, which is secured at its rear end to a bracket 22. The carriage is antomatically stopped at the rearward limit of its movement, and when so stopped by the means hereinafter described the laterally-projecting antifriction-wheel is left on the deadcenter or in alinement with the centers of the sprocket-wheel 18 and the sprocket-pinion 19, as clearly illustrated in Fig. 8 of the accompanying drawings.

The gear-wheel 20 receives its motion from a shiftable pinion 23, mounted on a shifting lever 24: and meshing with a pinion 25, which is mounted on .the shaft 26, which forms a fulcrum for the shifting lever. The shaft 26, which is a short or stub shaft, projects from the bracket 22, and the pinion 23 is adapted to be swung intoaud out of mesh with the gear-wheel 20 without disengaging it from the central pinion 25. This central pinion 25 is suitably fixed to or connected with a bevel gear-wheel 27, arranged vertically and meshiug with a transversely'disposed bevel-pinion 28, which is connected with a longitudinal ream-0 shaft 29, upon which a cone 30 is mounted. The bracket 22, which is secured to the rear end of the frame of the machine, is provided with an arm 31, which is boltedv or otherwise secured tothe rear end of the longitudinal supporting-bar 21, as clearly illustrated in Fig. L of the accompanying drawings. The bevel-pinion 28 may be provided with a hub or extension arranged in a suitable bearing of the bracket 22, as illustrated in Fig. 4c, and the hub or extension of the pinion 28 may be socured to the cone-shaft 29 in any suitable manner.

The cone 30 is rotated by means of a flexible elastic ring 32, interposed between the cone 30 and a reversely-arranged cone 33, which receives its motion for a suitable motor The motor 3 1, which is preferably operated by electricity, is connected by a belt and. suitable pulleys with the driving-cone 3?), and the elastic ring 32, which insures a rotation of the cone 30, encircles the driving-cone 83 and is adapted to be shifted longittuliually of the cones by the means hereinafter described, to vary the speed of the carriage, to cause the same to travel rapidly to and from the glass-tank, and to produce a slow move ment of the sprocket-gearing while the carriage is adjacent to the tank and while the operation of gathering a quantity of glass is being effected. By moving or shifting the ring 32 outward or rearward it is carried to the larger portion of the driving-cone and to the smaller portion of the cone 30, and the relative diameters of the active portions of the cones are thereby variei and the speed will be gradually increased as' the ring is carried outward, and by moving the ring inward it is carried toward the smallest portion of the driving-cone and the largest portion of the cone 30, and the speed of the carriage is consequently greatly reduced. The cones may be made of any desired size to secure the necessary variable speed to adaptthe machine for the class of work for which it is designed to be employed, and the change of speed is effected withoutjarring or jerking the carriage or the gathering instrument, hereinafter described. I

The ring 32, which is interposed between the reversely-arranged cones, is shifted to provide a slow movement of the carriage at the ends of its reciprocation and a rapid movement between the same, by means of a longitudinal rod 36, mounted in suitable guides 37 and 38 and provided at its rear end with a pair of antifriction-wheels 39, located at opposite sides of the ring and adapted to move the same backward and forward as the rod 36 is reciprocated. The guides 37 and 38 consist of brackets or arms secured to and extending approximately horizontally from the longitudinal supporting-bar 21. The movement of the rod is limited by means of adjustable collars 4:0 and 11, located at opposite sides of the arm or bracket 38, as clearly shown in Figs. 3 and 4. The spring is disposed on the rod 36 and is interposed between the arm or bracket 38 and the adjustable collar 40, which is located in rear of the said bracket or arm 38. The other collar 41 is located in advance of the bracket or arm 38, and it limits the rearward movement of the rod 36 by the spring 42, which is adapted to automatically carry the ring 32 backward to cause a rapid operation of the carriage. The adjustable collars are preferably provided with set-screws, and by adjusting the collar 41 the speed of the carriage when it is moving most rapidly may be regulated, and any desired speed may be obtained to adapt the machine to the character of the work for which it is operation has been completed and the carriage again moves rearward the coiled spring will advance and shiftthe ring 32 to the back of the di'ivingcone, and thereby increase thespeed of the carriage to cause the same to move backward rapidly. As the carriage nears the back of the machine the rod 36 is again shifted to reduce the speed by means of a transverse lever 45, fulcrumed between its ends on an extension of the arm or bracket 37 and hav ing its inner arm arranged in the path of a depending projection or pin 46, located adjacent to the said pin 44. The outer arm of the transverse lever is provided with a slot 47' for the reception of a pin or projection 48 of the rod 36, and when the inner arm of the lever 45 is moved rearward by the carriage the rod 36 will be thrown forward and the speed of the carriage will be again reduced; As soon as the coiled spring 42 is free to act it will again carry the rod 36 rearward and increase the speed of the carriage.

The carriage is stopped at the end of its rearward movement by means of a pivoted bar or lever 49, mounted on and extending transversely of the back of the carriage and arranged to engage the upper portion of the shifting lever 24, whereby the pinion 23 is swung out of engagement with the gear-wheel 20, as before explained. This operation is completely effected when the laterally-projecting antifriction roller of the endless sprocket-chain is at the dead-center before explained. in an upright position and the oscillatory shiftable gear 23 is located above the fulcrum of the lever. The lower end of the shifting The shifting lever 24 is arranged lever 24'is connected with a coiled spring 50, and its upper end is provided with an inclined arm or portion, as clearly shown in Fig. 1. The spring 50, which is located at a point beneath the lower rail 4, is connected at its outer end with a screw 51, having an adjusting-nut which is adapted to vary the tension of the spring. The screw passes through an opening of an arm which depends from the lower rail, and the nut engages the rear face of the arm, as clearly shown in Fig. 1. The motor is mounted on a suitable bracket, and it is located at the back of the machine at a point below the cone 3O. The pivoted bar or lever 49, which is provided at its outer end with a suitable grip or handle, is adapted to be swung upward out of engagement with the shifting lever when it is desired to start the carriage, and the spring 50 will then swing the gear 23 into mesh with the gear-wheel 20, and the carriage will be again moved forward. As, soon as the carriage is started it will continue its operation, and the pivoted bar or lever may be dropped upon the inclined upper arm or portion of the shifting lever, as it will not be necessary to hold the same in an elevated position until it is carried beyond the shifting lever by the forward movement of the carriage.

The top of the carriage may be secured to the vertically-disposed body portion in any suitable manner, and it is provided at its front end with eyes 52, which are hinged to corresponding eyes 53 of the hinged section 14 by means of suitable pintles. The hinged sec tion or member 14, which is advanced into the glass-tank, as illustrated in Fig. 1 of the accompanying drawings, is provided at its front end with suitable upwardly-extending bearings 54, between which is pivoted a bearing-bracket 55. The bearing-bracket, which forms the front portion of a pivotally-mounted holder, is secured to a plate 56, which forms the body portion of the holder, and this holder is adapted to receive a gathering-tool 57. The gathering-tool 57 is supported by antifriction rollers or wheels 58 and 59, arranged in pairs and located at the front and back of the pivoted holder, as clearly illustrated in Fig. 14 of the accompanying drawings. These antifriction-rollers, which permit a practically frictionless rotation of the glass-gathering instrument, may be mounted in any suitable manner, preferably by means of brackets secured to or forming a portion of the holder. The gathering instrument, which consists of a blow pipe or tube, is provided at a point intermediate of its ends with a gearwheel 60, having a hub or' central portion which is designed to be brazed or otherwise secured to the gathering instrument. This gear-wheel, which is located at the front of the holder, meshes with a corresponding gearwheel 61,'mounted on the front of the holder at one side of the gathering instrument and connected by a flexible shaft 62 with a shaft 6?), extending longitudinally of the carriage and jonrnaled in suitable bearings of the 1 same. The flexible shaft, which permits the holder to be arranged at any angle, is suitably coupled to the front end of the longitudinal shaft 63. The longitudinal shaft 63 has keyed or otherwise secured to it a transverse gear-wheel (it. which meshes with a pinion 65, which is slidingly mounted on a longitudinal shaft (56. The longitudinal shaft 66, which is arranged at one side of the main frame of the machine, is journaled at its ends in suitable bearings, and itis provided with a longitudinal groove 67, receiving a key ('38 of the pinion 65, whereby the latter is slidingly connected with the longitudinal shaft. The pinion 65 is located between a pair of arms 69 of the carriage, and the latter moves backward and forward it carries the said pinion 65 with it, whereby motion is communicated from the said shaft 66 to the gathering instrument in whatever position the carriage may occupy. The front end of the pivoted holder is provided with an upwardly-extending arm 7 0, which is connected by a longitudinal rod. 71 with an arm 72- of a short shaft 7 3, which extends through the central portion of the body of the carriage and which provided at the opposite side of the same with an arm 74:. The arm 74 depends from the shaft at one side of the body portion of the carriage, and the arm 72 extends upward at the opposite side of the carriage,the two arms and the transverse shaft constituting a lever which is fulcrumed on the carriage and which is adapted to be automatically operated at the end of the forward movement of the carriage to swing the arm forward and tilt the holder, whereby the gathering instrument is dipped into molten glass within the working chamber of the glass-tank.

The depending arm 7a is arranged to engage an adjustable device located in the path of the said arm 74 and consisting of a lever 75, fulcrumed between its ends on an arm of a bracket 76, and provided at its upper end with an antifriction-roller 77, arranged to ride on the arm 7% when the carriage nears the limit of its forward movement. The adjusting device forms a stop for the depending arm 7 t, and the continued forward movement of the carriage causes an oscillation of the lower arm Hand the upper arm 7 3, which depresses the front end or head of the gathering instrument. The upper arm of the lever 75 is connected with a s 'iring 78, which holds the lower arm of the lever 75 against an adjusting-screw 7 9, mounted in a threaded opening of a suitable support and capable of adjusting the lever to vary thedip or pitch of the gathering instrument. By throwing the upper end of the lever 75 forward the os c1llat1on of the arm 74 will be increased, and the movement of the gathering lnstrument will be correspondingly aifected. The spring 78 is secured. to the upper arm of the lever 75 and to the bracket 76, and it holds the lower end of the said lever 75 firmly against the adjusting-screw 79. The pitch of the gathering instrument may also be changed by means of an adjListing-screw 81, mounted in a threaded opening 'of a bracket 82 of the carriage and arranged over a longitudinal arm 83, extending rearward from the hinged section or member 14: and located at one side of the top of the carriage, as clearly illustrated in Fig. 5 of the accompanying drawings. By depressing the arm 83 the hinged section or member 14 may be elevated, and by raising the arm 8?) the section or member 1st will be depressed. By varying the pitch of the gathering instrument the latter may be caused, to dip to a greater or less extent into the molten glass, and it may be arranged to gather a maximum amount of glass on a minimumsized gathering-head. Also it may be arranged to gather the glass on the extreme outer edge of the head.

The gear-wheel 61 is permanently mounted in suitable bearings of the pivoted holder, and the said antifriction-wheels and 59 form open bearings for the gathering instrument, which may be readily lifted from the holder and replaced therein. The rear end of the grooved longitudinal shaft carries a sprocketwheel 8 which meshes with a sprocket-chain 85, that extends downward to a sprocket-mnion 86 of a cone-shaft 87. The cone'shaft 87 carries a cone 88, arranged similar to the cone 30, heretofore described, and cooperating with a reversely-arranged cone 89, mounted on the collar-shaft of the motor 34:, as clearly illustrated in Figs. 2 and 12 of the accompanying drawings. An elastic ring is interposed between the reversely-disposed cones 88 and 89 and is adapted to be shifted backward and forward in the same manner as the ring 32, heretofore described, to vary the speed of the gearing for rotating the gathering-tool to cause the same to rotate rapidly while gathering the glass and to rotate at a less rate of speed while the carriage is moving backward to prevent the glass from being thrown off the instrument by centrifugal force. This change of speed is effected without jarring or jerking the gathering instrument, and the lower portion of the elastic ring 90 is arranged between a pair of antifriction-wheels 91, located at the upper end of a shifting lever 92, arranged below the ITO is Vertically movable in suitable guides 98 of a bracket 99, is located beneath the rails 3 and 4 and has a coiled spring 99 disposed on it and interposed between thelower guide of the bracket and an adjustable collar 100, whereby the coiled spring is adapted to support the depressible shoe in an elevated position, as clearly illustrated in Fig. 2 of the accompanying drawings. Vhen the shoe is depressed, the shifting lever is oscillated and its upper portion is swung outward to carry the ring to the rear ends of the cones to reduce the speed of the gearing for rotating the gathering instrument. shoe is depressed and is arranged at a point below the rear portion 102, which is extended above the front portion of the shoe. The upwardly-projecting rear portion 102, which presents a convex face, is arranged in the path of a laterally-projecting antifriction roller or wheel 103, mounted on a depending extension of the carriage, as clearly shown in Fig. 16. When the carriage nears the front of the machine, it depresses the shoe, and the gathering instrument is rapidly rotated while it is being dipped into the molten glass, and this rapid rotation continues during the first portion of the backward movement of the carriage while the head of the gathering instrument is depressed and while it is gathering a supply of the molten glass. The glass is gathered on the backward movement of the gathering instrument to avoid plugging the opening or bore of the latter, and as the gathering instrument is raised from the glass of the working chamber the speed of the gearing for rotating it is reduced, and the said gathering instrument is slowly rotated to prevent any of the glass from being thrown off by centrifugal force. This reduction in the speed of the gearing for rotating the gathering instrument is effected by the sloping or inclined rear portion of the shoe engaging the laterally-projecting roller or wheel 103 of the carriage and permitting the shoe to partially rise, and as soon as the carriage moves beyond the shoe the coiled spring 99 will automatically lift the latter and shift the ring 90 to the inner or front ends of the cones to effeet a slow rotation of the gathering instrument. As the carriage nears the limit of its rearward movement a vertically movable forming-block 104 is lifted from a water tank or receptacle 105, located at the front of the frame of the machine and mounted on the bracket 76, as clearly shown in Figs. 1 and 2. The forming-block, which is of the ordinary configuration, and which is provided with perforations for the passage of water, is dipped into the latter to prevent it from becoming too hot, and it is connected at one side with a horizontal arm of a vertically-movable lifting-bar 106, arranged in suitable guides 107 and provided at its lower end with an antifriction roller or wheel 108. The lifting-bar is moved verti- The front portion 101 of the cally by means of a bell-crank lever 109, which is alsoconnected with a vertically-movable door or shield 110, adapted to cover the mouth or opening 111 of the glass-tank to protect the operator and to confine the heat within the tank, and thereby lessen the consumption of gas. The guides 107 are located at the top and bottom of the water tank or receptacle 105, and the bell-crank lever, which is fulcrumed at its angle, has a long forwardly-extending arm and is provided with a short rearwardly or upwardly extending arm. The roller 108 is arranged in the path of the forwardly-extending arm of the bell-crank lever 109 and is engaged by the same when the lever is oscillated by the carriage, as hereinafter explained. The said forwardly-extending arm of the bell crank lever 109 is also connected by a link 110 with the vertically-movable shield or door 110. The shield or door is provided with depending stems 112, arranged in suitable guides 113, located at a point beneath the opening or mouth 111 and extending forward from the front end of the frame of the machine; The door or shield is constructed of asbestos. and the bell-crank lever 109 is capable of simultaneously raising the forming-block and the door or shield. The upwardly-extending arm of the bell-crank lever 109 is provided with an adjustable bar or member 114, pivoted between its ends to the upper terminal of the short arm of the lever 109 and provided at its lower end with a curved arm or portion 115, having a longitudinal slot receiving a suitable fastening device 116. The fastening device 116, which is mounted on the short arm of the bell crank lever 109, extends through the curved slot of the arm or extension 115 and is adapted to clamp the adjustable bar or member 114 in the desired position. The pivot of the bar or member 114 is preferably provided with a clamping-nut to assist in securing the said bar or member in its adjusted position. The bar or member 114, which constitutes a portion of the bell-crank lever, is arranged in the path of the pin 117, which extends laterally from the lower portion of the car, and as the latter nears the limit of its backward movement the pin 117 is carried into engagement with the adjustable member of the bellcrank lever 109, and the latter is oscillated to raise the block and the door or shield. The pivoted bar or member is capable of adjustment to cause the forming-block and the door or shield to move vertically at the proper time. As soon as the carriage moves forward and releases the bell-crank lever 109 the formingblock and the door or shield will drop automatically by gravity and will remain in such lowered positions as illustrated in Fig. 1 of the accompanying drawings while the glassgathering instrument is being operated within the working-chamber of the glass-tank. The door or shield will remain closed and will protect the operator from the heat of the glasstank while the glass on the head of the gathering instrument is being worked. The forming-block receives the glass on the end of the gathering instrument, which is continuously rotated until it is lifted out of the holder by the operator.

It will be seen that the inclination or pitch of the glass-gathering instrument may be readily changed by adjusting the lever and the hinged member or extension uponwhich the pivoted holder is mounted and that by changing the pitch or inclination of the gathering instrument the latter may be caused to project to a greater or less extent into the glass and to gather the same at the extreme outer end of the head and to collect a maximum amount of glass on a minimum-sized head. Also it will be seen that the means for automatically changing, the speed for operating the carriage and for rotating the gathering instrument enable such results to be accomplished without jarring or jolting the gathering instrument or the machine. Furthermore, it will be apparent that the door or shield is automatically closed to protect the operator from the heat and to confine the latter within the chamber of the tank, and tl'lereby lessen the consumption of gas or other fuel for maintaining the contents of the tank at the proper temperature. The pivotally-mounted gathering-instrument holder, which is capable of adjustment on the carriage, is automatically carried from an approximately horizontal position to an inclined position as it is projected into the chamberof the glass-tank, and as the carriage moves backward it is returned to its horizontal position, and the forming-block is automatically elevated and arranged to receive the glass on the instrument, which is rotated by the machine until it is removed from the holder.
